The IPL range use a tapered full length line
damped with profiled foam and long haired wool to produce; superior more extended
bass, and a more open, natural, and musical sound quality. IPL have been
designing Transmission Line for over 15 years

In order to get the best performance it is essential to select the correct
speaker for your room. and place the speakers in the optimum position. IPL
Transmission Lines are free-standing loudspeakers which produce low bass. In
order to get the best results please follow the guidelines listed below;

1) In the speaker specifications there are minimum room sizes listed.
Whilst these are only rough guidelines, ( there are many positive factors
involved which can improve room acoustics, such as room damping with carpets,
curtains and soft furnishings) if there is any doubt it is probably best to opt
for a smaller IPL TL model or a stand mounted IPL design (The M3m Ribbon, SM1, and SM2
Ribbon are ported speakers which use the same drivers as the M1tl , S2TLK, and S4tl
respectively and will be less sensitive to room positioning and room size.)

2)For best results it is important that the speakers are symmetrically
placed, firing down the length of the room, at least 10" from the rear wall and
at least 18" from the side walls (This is especially important with the S4tl and
S5tl) . If your room is square then you will experience a double room resonance
which could be problematic with all speakers that produce low bass . Once again
if in doubt opt for a smaller TL or a stand mounted design. You are welcome to phone for advice on
speaker selection.

3)All these speakers will benefit from bi-wiring with a good cable such as
the Vandamme studio cable listed in the cables section.
